Scenario/Turn text located
I’ve found it!
It’s not in the game at all … When checking the Langrisser II Megadrive scripts, I located the same text. Then I beat Langrisser II just to test. It is a second ending scene missing in Der Langrisser, where it shows you how many turns you took to beat each scenario.
This is likely a holdover much like “Mystery Knight,” which also appears in the Der Langrisser scripts despite not being in the game.
So, we can rest easy. This text isn’t going to show up to bite us in the ass post-release. I’ve formatted it matching how it would appear in the Megadrive game, just as a precaution.
